SPEOIFICATION,.orming part of Letters IlPatent No. 761,429, dated. May 31, 1904. Application filed October 10,1903. SerialNo. 176.518. (NomodelJ-l To all whom, it may concern:

Be it known that we, GEORGE L. VOG'EL and ANTI-IONYFINO'K,citizens of the United States,

residing in Jersey City, in thecounty of Hudson'and State of New Jersey, have invented certain new and useful Improvements in Ma: chines for Bending Angle-Irons, of which the following is a specification.

This invention relates to certain improvements inmachines for bending angle-irons, T- bars, Z-bars, and similar structuralshapes, the machine -being designed so as to incl'ose the angle-bars by two sets of r'oll's a horizontal set and a vertical set adjacent to the horizontal set and at right angles thereto, but in such a manner that each set of rollsreceivesa direct positive motion by suitable transmission from the driving-shaft, so as to'fully inclose the angle-ironand force it through between the two sets of rolls without being distorted or Warped; and for this purpose the invention consists of a machine for bending angle irons, whichcomprises a'set of bending-rolls, a set of guiderolls' mounted to revolve'in a plane at right angles to the plane'of the bending-rolls, each set comprising a pair of outer rolls for engaging one side of the angle-iron, and an intermediate third roll forengaging the opposite side thereof, the rolls 'of onc setbeing. arranged adjacent to the corresponding rolls of the other set, and mechanism fortransmitting direct positive motion in proper direction to cachroll. 7 i

The invention consists, further, of the combination, with'the two sets 'of, bending and guiding rolls, one set being arranged at right angles to the other set of rolls'and each consisting of a pair of outer'rollsand an intermediate thlrd roll, of mechanism for 1m parting positive motion to each roll'of both sets and mechanism for adjusting some of the rolls of each set so as to permit the bending of the angle-iron to different degrees of curvature;

and the invention consists, lastly, of certain additional details of construction and combinations of parts, which will be fully described hereinafter and finally pointed out in the claims.

Referring to the drawings, A, B, and 0 represent threeupright standards suitably bolted to the floor. theintermediate and O, the rear standard, of

The standards are approximately of the same size and shape and having some portions broken out for permitting access to the mechanism between the separate standards. ployed -a bending set consisting of two lower rolls 1) Diand an upper roll D and a guide setfconsistingof three rolls, two rolls of which are on one side of the iron, while the third "roll is on the other side of the same. rectangular angle-1rons the bendmg-rolls'are For arranged horizontal and the guide-rolls are arranged vertically thereto. driven by positivemotion, whereby the angle-ironis moved from one end of the machine to the other and bent in a reliable and effective manner to the curvature desired. The adjacent ends of these rolls are provided Two sets of rolls are em- A is the front standard, and B l All the rolls are with bevel-gears, so that rotary motion is imparted by direct transmission from the primary rolls to the supplemental rolls adjacent thereto. The left-hand primary roll is mounted on a shaft S, to which motion is imparted by a belt-and-pulley transmission from an overhead shaft, the belt being thrown to a' loose pulley by suitable shifting mechanism (not shown) when the motion of the machine is to be interrupted ormoved from the loose pulley to the fast pulley when motion is to be imparted to the bending-rolls. The drivingshaft S is supported in journal-bearings of the three standards A. B, and C. On the front end of the driving-shaft and on that part of the driving-shaft located between the standards B and C are mounted transmitting gear-wheels g, which transmit motion by intermediate gear-wheels g to gear-wheels g on the shaft S of the outer primary bendingroll D, so that rotary motion in the same direction as the primary roll D is imparted to the second primary roll D. The shafts of the intermediate transmitting-gears g are supported on stud g, connecting straps g g that are mounted, respectively, on the driving-shaft- S and the auxiliary shaft S, as shown in Fig. 4. By the two sets of transmitting-gears g g on the shafts S S auniform motion parallel with each other is imparted to the primary bending-rolls D D, and thereby to the supplemental rolls G G, which are placed in mesh with the same.

The intermediate primary bending-roll D mounted on shaft S receives motion fromthe primary driving-shaft S by intermediate transmitting-gears f f f f These transmitting-gears are shown clearly in Fig. 8 and are arranged for the purpose of permitting the adjustment of the intermediate primary bending-roll D to any position within certain limits parallel with the rolls D and D and still the gears be in mesh, so as to be rotated from the driving-shaft S. For this purpose an elbow-shaped strap f is journ aled on the shaft S-and has its other end pivoted by stud f to strap f, which latter is journaled on shaft S A gear f is secured on shaft S adjacent the elbow-strap and meshes with a gear a f, journaled at the bend of said strap. A gear f is secured on shaft S adjacent the link f, and a gearf is journaled on studf and meshes with both gears f and f As-the shaft S of the intermediate primary bending-roll D is made vertically adjustable within certain limits, so as to permit the bending of angle-irons of differentheights, the journal-bearings of the roll D have to be adjusted in the guide-openings of the standards A, B, and C. By the adjustment of the shaft S of the roll D the intermediate gears and their straps are correspondingl y adjusted, while they are always retained in mesh with each other and the gear-wheel f on the driving-shaft S, so that whatever be the position of the roll and the shaft continuous rotary. motion is imparted to the same from the driving-shaft S; On the rear end of the shaft S is mounted a gear-wheel p, which meshes With a gear-wheel p on a shorter shaft S which is supported in journal-bearings of the rear standardO and in bearings of an auxiliary sup port B, which is guided in the opening of the intermediate standard B, said shaft S"serving to transmit, by means of bevel-gears p p, direct positive motion to the intermediate vertieal roll G as this roll cannot receive motion from its primary roll, for the reason that it has to be adjusted relatix ely to the same. The guide-roll G is rotated from roll D by bevelgear (1.

By the sets of transmitting gear-wheelsdescribed direct rotary motion is imparted to the primary bending-rolls D D D and by the bevel-gear transmission between the primary and supplemental rolls D G and D nr rotary motion to the outer-supplemental rolls G G, while independent rotary motion is imparted to the intermediate primary roll I) and to the intermediatesupplemental roll G from their transmitting-gears; but all the primary rolls are rotated by the transmitting gearwheel mechanism described in the same direction, and also the supplementary rolls, so as to act simultaneously on opposite sides of the angle-iron that is fed and moved forward between the rolls and produce the coaction of all the rolls on the same and the bending without lateral dislocation or warping of the angleirons. The bending and guiding rolls act simultaneously by their positive rotary motion on the angle-irons and produce the bending of the same in a reliable and effective manner according to the curvature to which the rolls are adjusted.

For the purpose of bending the angle-iron to any desired degree of curvature the outer right-hand primary and supplemental bending-rolls D Gr are made adjustable both in vertical and horizontal direction by the adjusting mechanisms shown in Fig. 6. The roll D is for this purpose supported in a journal-bearing which is made adjustable in hori- Zontal direction by a screw-spindle m, which is swiveled to the journal-bearing of the shaft S and which is guided in a stationary nut m attached to a bracket an, as shown in Fig. 4. The screw-spindle m is turned by a suitable handle so as to permit the easy adjustment of the primary bearing of the shaft S. These bearings are guided in larger oblong guideframes m, that are guided in vertical ways of the standards A and B and that are adjusted vertically on said ways by a screw-spindle '21, that is swiveled to the under side of said guideframes, to which rotary motion is transmitted by a bevel-gear 12 71 of which 11 is provided with a screw-nut meshing with the screw-spindle 12/, while 12 is placed on a shaft a", that turns in bearings at the lower part of the standards A and B, as shown in Figs. 5 and 6. By these adjustable guide-frames the journalbearings of the shaft S and the roll D can be adjusted in both vertical and horizontal direction, according to the curvature imparted to the angle-iron. The vertical roll G is supported in bearing-block (13, that is made a part of the journal-bearingsof the primary roll l).

Hence the supplemental roll G is simultaneously adjusted with the primary roll D, as will appear from detail Figs 2.

The intermediate rolls G and D of both' sets of rolls are adjusted independently of each other. As the journal-bearings of the shaft S of the primary. roll D are supported in the guide-openings of all the three upright stand- 1 ards A'B (J, it is necessary to simultaneously adjust these bearings. This is accomplished by means of screw-spindles that are swiveled to the upper end of the journal-bearings /L and 72 of the shaft S and guided insleeves 7t I at the upper ends of the standards A B C, said simultaneously turned in the same direction,

- and with the primary roll D the motion-transand thereby theroll. D raised or lowered as required bythe curvatureto be imparted to the angle-iron. For the purpose of adjusting simultaneously the roll G of'the supplemental set of bending-rolls the entire journal-bear.-

ings, of the'shaft S? in the standard B-is provided with a U-shaped extension vat its upper side, in which the upper angular end of the shapedextension is connected by a set-screw p with the rearwardly-projecting upper end of the support B, so that the latter is moved with the intermediate, bearing of the shaft S in upward or downward direction. As the bearings of the auxiliary shaft S are located in the standards B and (3,, the rear bearing is connected with the rear bearing of the lowered simultaneously with the transmitting bevel-gear 22 19 so that at whatever point they supplemental roll G is adjusted relatively to mitting mechanism will act on the shaft of the roll G which is supported in neck-and step bearings of thesupport B, as shown in Fig. 7 As it is necessary, however, to impart a certain degree of adjustmentto the supple' mental roll G in forward or backwarddirection, the vertical support if can be adjusted by the set-screw, the inner end of which is swiveled to the upper angular end of the support,

while the shaft S is connected by a spline with the pinion of the bevel-gear, and the support B can be moved withthe' roll D and the bevelwhe'el in forward and backward direction,so that the supplemental roll Gdremains in adj ustment with the primary roll D so that they bear on the side and end of the angle-iron to be bent and produce thereby the hugging of the same on its bottom,- sides, and ends, so as to keep it within full control during its motion through the primary and supplemental bending-rolls at whatever curvature the outer right-hand bending rolls and intermediate bending-rolls are adjusted.

Having thus described our invention, we
